Illuminate your property at night. Don't depend on streetlights or lights from adjoining properties. Leave outside lights on after dark. Make sure there are no shadows or dark areas around the house, garage, or yard in which a person could hide. Check lights regularly and replace burnt out bulbs. Protect your lights from vandals with wire covers. Be sure your lights don't shine into the eyes of passing motorists or police patrols. Padlock your circuit breaker box to prevent lights from being turned off. Good four-corner exterior lighting is important, particularly where there are dark areas around the house. Floodlights installed under eaves can illuminate these areas and expose anyone next to the house. Timers or photoelectric cells can be used to turn lights on at dusk and off at dawn. And motion sensors can be used to turn lights on when any motion is detected.
